What is the percentage dissociation of HI at 444°C, if the experiment is started with one mole of HI — Chemical Equilibrium Chemistry Question
Question
What is the percentage dissociation of HI at 444°C, if the experiment is started with one mole of HI(g) and one mole of I₂(g)?
Answer: A
💡 Solution & Explanation
According to Le Chatelier's principle, adding a product (I₂) to the reaction mixture at the beginning will shift the equilibrium in the backward direction (towards the reactants). This suppresses the dissociation of HI. Consequently, the percentage dissociation will be less than the standard 22.22%. Therefore, correct answer is A.
